7Then he inserted the poles into the rings on the sides of the altar, with which to carry it. He made it hollow with planks.

81Moreover, he made the basin of bronze with its base of bronze, 2from the mirrors of the serving women who served at the doorway of the tent of meeting.

93Then he made the courtyard: 4for the south side the hangings of the courtyard were of fine twisted linen, a hundred cubits; 10their twenty pillars, and their twenty bases, were made of bronze; the hooks of the pillars and their 5bands were of silver. 11For the north side there were a hundred cubits; their twenty pillars and their twenty bases were of bronze, the hooks of the pillars and their 6bands were of silver.
